The Manini, Convict Tang, is one of the most common fish found among the Hawaiian reef. You can spot them right away due to their striped skin and slightly green tone. Another fish known as Mamo looks similar to the Manini, but you can separate the two by the Manini's stripe through its eye. I love watching the little Manini swim along the reef. They are party fish and love to hang out in groups. During the day they have their fun, then at night it is time to stay still and avoid the larger hungry night fish.
